Lindsay Lohan parties with Paris Hilton

Lindsay Lohan and Paris Hilton were once close friends. But much like Hilton’s friendship with Nicole Richie, they had a falling out.

Just this past weekend, however, the two former friends reunited at a Malibu beach party at Hilton’s house.

“Everyone was so surprised when Lindsay walked in and we thought they didn’t get along. But they immediately gave each other a big hug,” a source for TMZ said.

Lohan, along with other A-list guests such as Emma Roberts, Lukas Haas, and Paris’s sister, Nicky, partied on the beach, hung out in the hot tub, and had a “mini dance party.”

Hilton “loved seeing her again," the source added.

Lohan, who was freed from house arrest last month, was reportedly on her best behavior and wasn’t seen drinking any alcohol.

The Daily Mail reports that she did, however, smoke some cigarettes and leave “arm-in-arm” with Australian actor Brett Tucker.
